On May 10th, 1912. a decree was issued that made the proof of rough bored tubes optional as of June 1st, 1912. And again, all of this jockeying for position in Proof Procedures was driven by the Germans, and the English to a lesser extent. But all this would have come to a consensus in 1914 @ the Proof Council had not the 1st Major Disagreement in Europe been kicked off...... So the proof standards, with metal technology & powder advances jockeying for position also, would have to wait another decade.
